Con: Contrast-induced nephropathy-should we try to avoid contrast media in patients with chronic kidney disease?

Abstract

The incidence of acute kidney injury (AKI) attributed to iodinated contrast has been over-estimated and this has led clinicians to withhold potentially life-saving diagnostic and therapeutic interventions. There is mounting evidence that iodinated contrast plays only a minor role in the development of AKI in comparison with more significant risk factors such as preexisting renal dysfunction, hemodynamic instability and exposure to nephrotoxic drugs. We will present data which challenge the dogma of avoiding iodinated contrast in patients with reduced renal function. Based on a rational and individualized risk-benefit analysis, we believe it is preferable to utilize iodinated contrast if alternate diagnostic or therapeutic options are comparatively ineffective or hazardous.
